Vegan "white sauce"?

["Kate Pugh" <katherine.sheppard@xxxxxxxxxxxxxxxxxxxxxxxxxxx>]

Here's a challenge for you all. I need a fatfree vegan sauce
which can be used as a substitute for white sauce for eg binding
vegetables for pies. Basically I want something tasty and thick
which doesn't use soya milk or similar, and doesn't have too
strong a flavour of its own.  

Thanks in advance,

Kate
